lVith the above and other objects in view this invention relates to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a horizontal sectional view of two of the tanks of a tank farm, showing the branch pipes, of the outlet line, connected into said tanks and equipped with the improved type of valve mechanism.

Figure 2 shows a fragmentary vertical sectional view of a tank showing the valve mechanism therein shown in section, and

Figure 3 shows an end View of the valve mechanism partly in section.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures the numerals 1 and 2 designate two of the tanks of a tank farm into which are connected the branches 3 and 4 of the main outlet line 5. Outside of the tanks these branch lines are equipped with the respective shut of valves 6 and 7.

W'ithin each tank there is a valve casing, as 8, substantially, tubular in form. This casing is secured, at its outer end, to the tank wall in alignment and communication with 0 the corresponding branch line and the inner end of the casing has an inlet opening 9. The casing 8 has a horizontally disposed lengthwise partition 10 and above it the transverse partition 11, thus separating the casing into 36 a flow chamber 12, an inlet chamber 13 and an outlet chamber 14. The arrangement of these partitions may, of course, be changed to provide the chambers referred to, the specific arrangement shown not being essential.

The chamber 13 communicates with the interior 0]": the tank, through the opening 9 and the chamber 14 communicates with the corresponding branch line.

The partition 10 has an opening through which the chamber 18 may communicate with the chamber 12, and this opening is surrounded by the valve seat 15. Upstanding from the casing 8 and aligned above the seat 15 there is a tubular valve guide 16 having opposing,

.50 aligned vertical bearings 17. Vertically movable in said guide is a sleeve valve 18, whose lower end is closed and tapered to conform to, and close, the seat 11. The valve 18 has laterally extending rods 19, 19, fixed thereto and workin through the respective bearings 17 and attac ed to the outer ends of the rods 19 are the relatively large cylindrical floats 20, 20, preferably formed of sheet metal.

Leading from the flow chamber 12 into the outlet chamber 14 there is an opening having a surrounding seat 21 and an upwardly opening back pressure valve 22 controls said opening. This valve has an upstanding stem 23 which works in a guide 24 attached to the upper side of the casing 8.

At the present time when the contents of an oil tank is delivered into the line the corresponding, gate valve, as 6 or 7 is opened and the oil is thus permitted to drain out,

but while being drained the presence of an attendant is necessary to close said opened gate valve before the inner end of the branch line connected into said tank is uncovered and air entrapped in said line. WVith the type of valve herein described the presence of an attendant is not necessary as the valve 18 will automatically close before theinlet 9 is uncovered and exposed to the air. Furthermore both of the tanks 1 and 2 and the other tanks of the farm, connected into the line 5, may be drained at the sametime andthe back pressure valves 22 will prevent the back flow of fluid from one tank into another.

While I have shown what I now consider the preferred form of the invention it is obvious that mechanical changes may be made therein and equivalents substituted for the parts shown and I reserve the right to make such changes and substitutions as may be found desirable and such as may be comprehendedwithin the scope of the appended claims. I

What I claim is l. A valve mechanism for controlling the flow of fluid from a tank and including a 9 casing anchored to the tank and having an inlet in the tank and an outlet, partitions fixed in said casing separatingthe same into an inlet chamber into which said inlet leads, an outlet chamber from which said outlet leads and a flow chamber, openings connecting the flow-chamber with the inlet and outlet chambers, and surrounded by valve seats, and valves controlling said seats, and a float con nected to one of said val es, a valve guide attached to said casing in which one of said valves works, a float outside of the guide connected,'to said lastnamed valve, and means limiting the range of movement of said valve.

2. A valve mechanism including a casing having an inlet and outlet, partitions in said casing separating the same into an inlet chamher into which said inlet leads, an outlet chamber from which said outlet leads, and a flow chamber, openings connecting the flow chamber with the inlet and outlet chambers, and surrounded by valve seats, valves con trolling said seats, a float connected to one of said valves, a tubular valve guide attached to and upstanding from said casing, having a vertical bearing and in which one of said valves Works, a float outside of the guide, and means working laterally through said bearing, and fastened to said float and to the valve in said guide.

3. A valve mechanism for controlling the outflow of fluids from a tank and comprising a casing within and anchored to the tank and having an inletwithin the tank and an outlet from the tank, partitions fixed in said casing separating the same into an inlet chamber into which the inlet leads, an outlet chamber from which said outlet leads and a flow chamber, there being openings surrounded by valve seats and connecting the flow chamber with the inlet and outlet chambers, valves controlling said openings and arranged to be closed by gravity, a tubular valve guide standing up from the inlet chamber in which the valve controlling the corresponding seat is fitted, said guide having avertical slot, a rod attached to the said valve and extending out through said slot and a float fixed to the, outer end of said rod.

In testimony whereof I have signed my name to this specification.
